Reception apparatus and transmission apparatus

Abstract

Provided is a reception apparatus that includes an information processing section configured to generate an image at least either in a first mode for reading out a whole captured region or in a second mode for reading out a partial region in the captured region. At the time of readout in the second mode, the image processing section varies a readout rate depending on the region.

The invention claimed is: 
     
       1. A reception apparatus comprising:
 reception circuitry configured to receive data; and 
 an information processor configured to generate an image, based on image data output from the reception circuitry, wherein 
 the reception circuitry outputs, in a first mode, a whole captured region as the image data and outputs, in a second mode, a partial region in the captured region as the image data, the reception circuitry selecting among the first mode and the second mode on a basis of additional information included in the image data, the selecting among the first mode and the second mode being automatically performed in an absence of a user selection of a region. 
 
     
     
       2. The reception apparatus according to  claim 1 , wherein
 the information processor generates the image by combining plural images of the image data received in the second mode. 
 
     
     
       3. The reception apparatus according to  claim 2 , wherein
 the information processor determines the number of images to be combined of the image data received in the second mode. 
 
     
     
       4. The reception apparatus according to  claim 1 , further comprising:
 transmission circuitry configured to transmit region information data to an imaging apparatus, wherein the information processor generates the region information data, by determining the partial region to be acquired of the captured region, based on the image generated in the first mode. 
 
     
     
       5. The reception apparatus according to  claim 4 , wherein
 the size of the region in the second mode is determined by an exposure time in the second mode and by an exposure time in the first mode. 
 
     
     
       6. The reception apparatus according to  claim 1 , wherein
 the information processor generates information representing coordinates and the size of the region in the second mode as the region information data, the information processor further supplying the generated information to the reception circuitry. 
 
     
     
       7. The reception apparatus according to  claim 1 , wherein
 the information processor uses the region read out in the second mode and any other regions than that region when generating the image in the first mode in a frame immediately following readout in the second mode. 
 
     
     
       8. The reception apparatus according to  claim 1 , wherein
 the reception circuitry receives a transmitting signal in which a payload part of a packet includes the image data and in which a predetermined header part includes the additional information. 
 
     
     
       9. The reception apparatus according to  claim 8 , wherein
 the information processor extracts region information regarding the region from the header part included in the transmitting signal received by the reception circuitry, the information processing circuitry further extracting, on a basis of the extracted region information, the image data of the region from the payload part included in the transmitting signal received by the reception circuitry. 
 
     
     
       10. The reception apparatus according to  claim 9 , wherein
 the region information includes information indicative of the size of the region and information indicative of the number of frames of the image transmitted in the region. 
 
     
     
       11. The reception apparatus according to  claim 8 , wherein the reception circuitry receives the signal according to the MIPI (Mobile Industry Processor Interface) CSI (Camera Serial Interface)-2 standard, the MIPI CSI-3 standard, or the MIPI DSI (Display Serial Interface) standard. 
     
     
       12. A non-transitory computer readable medium storing program code, the program code being executable by a processor to perform operations comprising:
 generating an image based on image data; and 
 selecting among a first mode and a second mode, wherein 
 in the first mode, a whole captured region is output as the image data and, in the second mode, a partial region in the captured region is output as the image data, and 
 selecting among the first mode and the second mode is on a basis of additional information included in the image data, the selecting among the first mode and the second mode being automatically performed in an absence of a user selection of a region. 
 
     
     
       13. The non-transitory computer readable medium according to  claim 12 , wherein the operations further comprise:
 generating the image by combining plural images of the image data received in the second mode. 
 
     
     
       14. The non-transitory computer readable medium according to  claim 13 , wherein the operations further comprise:
 determining the number of images to be combined of the image data received in the second mode. 
 
     
     
       15. The non-transitory computer readable medium according to  claim 12 , wherein the operations further comprise:
 transmitting region information data to an imaging apparatus; and 
 generating the region information data, by determining the partial region to be acquired of the captured region, based on the image generated in the first mode. 
 
     
     
       16. The non-transitory computer readable medium according to  claim 15 , wherein the size of the region in the second mode is determined by an exposure time in the second mode and by an exposure time in the first mode. 
     
     
       17. The non-transitory computer readable medium according to  claim 15 , wherein the operations further comprise:
